Game companies really want you to buy Wii U versions of their games, including Tecmo Koei and their upcoming Ninja Gaiden 3: Razor's Edge. This Wii U launch title will be releasing alongside Nintendo's console November 18, and it packs free DLC, and other content that should make it more robust than the original Ninja Gaiden 3 for PS3 and Xbox 360.

What sort of content? Mostly what you might expect. Razor's Edge will include new weapons and characters, plus a redesigned battle system and multiplayer modes; though keep in mind voice chat is pretty sketchy for Wii U games right now. Anyway, the Wii U edition will actually boast six weapons over the original three: Sword, Claws, Scythe, Dual Katana, Staff, and Kusari-Gama. The number of available Ninpo will also be expanded to three.

Here are some other Wii U exclusives to keep in mind:

Ayane as a playable character: In previous versions of the game, Ayane appeared only briefly in one cut scene. Now players can help her progress through her own exclusive chapters using a special set of weapons and Ninpo attacks.

Character-progression system: Using Karma points earned during game play, players can upgrade weapons and Ninpo, learn new moves, increase their HP level and unlock new character costumes.

Ryu and Ayane playable in co-op mode: For the first time, players can use Ryu or Ayane to represent themselves in the game’s online co-op mode.

Test of Valor battle areas: Each chapter includes a hidden battle area called Test of Valor. Upon finding hidden Crystal Skulls, players will be transported to these areas to face down waves of enemies and classic NINJA GAIDEN boss characters with new moves.

Wii U GamePad Functionality: Using the Wii U GamePad, players can easily change weapons or Ninpo attacks, and also quickly reference the button inputs required for various combo attacks without ever stopping the action.

Additional Playable Characters: After the launch of the game, additional playable characters will become available as free downloadable content. More information about these characters will be revealed at a later time.

More Tenacious Enemies: The Wii U version of the game restores enemies’ ability to fight when severely wounded, requiring players to stay nimble with their battle strategies.

As for the original, we weren't too keen on Ninja Gaiden 3. But hey, maybe the Wii U version can offer something better.
